Specification of Letters Patent.

Patented July 20, 1909.

Application filed January 15, 1909. Serial No. 472,461;

To all whom it may concern:

Be it known that l, llnunnn'r S. HUM- Pinter, a citizen of the United States, residing-z t Kalamazoo, county of Kalamazoo, and State of Michigan, have invented. certain new and useful Improvements in Water Heaters, of which the following is a specilication.

This invention relates to improvements in water heaters.

The main objects of this invention are: i irst, to provide in a water heater on l1T1- proved valve mechanism whereby the fuel valve is controlled to maintain a con1porstivcly oven temperature on the water drown, although its volume varies. vide in a water heater an improved valve mechanism for nutoiuat'ically controlling the temperature of the water drawn from the heater, and also the tonuieraturc of the water in the heater when the drawing of the writer ceases. 'lhird, to provide in a. water heater, an improved valve mechanism whereby the fuel valve is antomnticnlly controlled by the water drawn from the heater and by the thormordat which roaot one with the other. Fourth, to provide in av paler heater on im proved pilot flashing means whereby the pilot is autonurtimrlly controlled by the \VtttOl'. i

Further objects, and objects relating to structural details, will definitely appear from ill the detailed description to follow.

I. accomplish the objects of my invention by the dcv'ces and means described in the following specification.

The invention clearly delined. and] pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the second panyine' drawing, forming it part of this specs licatioli, in which- Figure 1 is a detail elevation of a water heater structure embodying the features of my invention, a. portion of the heater casing being broken away to better show the arrangement of the ports. Fig. 2 is on onlarged detail vertical section through the valve meeluinisni, taken on a line correspending; to line 2----2 of Fig. l. enlarged detail, partially in vertical section,

Second. to pro-.

Fig. 3 is an of a, line corresponding to line 3--3 of Fig. 2. Fig. l is an enlarged detail section taken on a line corresponding to line 4 4 of Fig. 2, showing details of the pilot valve and its connection. 5 is a detail section taken on a li ue correspomling to line'5'5of Fig.

In the drawings, similar reference char meters refer to similar parts throughout the several views, and the sectional views are talten looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the heater 1 is of the coil type, the some being provided with a plurality of coils 2, arranged in vertical series. The casing of the heater is preferably double walled, as illustrated, to preventrm diation. The burners 3v are arranged in the base of the heater below the coils. The wotor supply in the structure illustrated, is con,- nected to the heater through the valve casing 4, which is provided with a water inlet 5 connected to the water supply pipe 6, and with a, discharge 7 connected to the heater through the inlet pipes 8 at the upper ends of the heater coils. lhe valve casing is also provided with a. hot water inlet El and it hot water discharge 10, the discharge being eontrolled by a regulating valve 11. The hot water discharge 10 is connected to the house system or to a delivery pipe, provided in the structure illustrsted with a.

faucet, as 13,t,he faucet being illustrated only to indicate the operation of the heater.

The hot water inlet or p ossage 9 is connected to the discharge pipe i l-"from the lower end of theheeter coils, preferably through the thermostat tube 38. The hot water inlet 9 is preferably connected to the cold Water discharge 7 through a circulation-port 15, so that when the circulation port'f li is open the water may circulate through the heater and the thermostat, this structure of the valve casing being substantially that illustroted in my application for Letters Patent filed November 23, 1908, Serial No. 464,121.
